Solved Not much to go on but someone might be able to identify

I run a charity plant sale and occasionally I am given plants to add to those I sell from my own garden.
Someone donated a load of plants to me today. I know what all of them are except 1. The herbaceous plant flowers in Julyish, puts up quite tall stems of white flowers and the leaves grow in a sort of rosette. All I can show is a photo of the leaves. The plant sort of reminds me of Verbascum Chaixii but that is a biennial and the person who donated it says he has grown it for a few years. Hope someone can help as not clever to try and sell something I don’t know the name of!

 

Possibly Verbascum phoeniceum? There is a white form and (for me) they are perennial for a few years at least.

 

Thank you @JennyJB I have had a look on the net and you may well be right that the plants I have been donated are Verbascum Phoeniceum Alba.I have messaged the person who gave me the plants to ask him to look on the net and confirm the plants are as above. Have you ever split up and repotted this plant? as I can see there are quite a few plants in the clumps which I could split up. That said I do not want to sell plants which are going to “ leg up” quickly. Maybe I might grow it on myself to see how it behaves. Good shout tho pretty certain you are right.

 

I've never tried splitting them. I just grow more from seed if I want more - they germinate easily. The purple one "violetta" sometimes self-sows for me.

 

Small correction - Verbascum chaixii is a perennial - Verbascum chaixii | nettle-leaved mullein Herbaceous Perennial/RHS, Dry Areas | Verbascum Chaixii - The Beth Chatto Gardens .

 

Oh that is interesting. Must be my climate as I have never had it survive once having flowered so presumed it was a biennial.

 

That explains it. I've had it as an unexpected arrival (in Cambridgeshire) but in an inconvenient (to the plant) place, where it flowered and persisted for a few years. This summer I cut up the tap root into bits hoping to propagate it (not the best time perhaps); two bits have produced leaves that I now need to shepherd through winter.

 

@micearguers I have grown Chaixii from seed easily. Never got any self sown so probably due to wet in the winter but totally trouble free from saved seed…..
Slight snag! The last Chaixii I had, guess who forgot to save seed? By the time I got round to trying to collect any there was zero in the pods having been scattered far and wide never to be seen again.
